If you are using the full version of Excel 2013 (earlier versions are not as tightly integrated with OneDrive and student or demo trial versions may differ) you will see a reference to OneDrive when you click File-->Save As. You will not see my OneDrive account (M Smart). In the videos and book I use my own OneDrive account to demonstrate OneDrive features. Instead, you will see the name you gave to your own OneDrive account (assuming that you have registered one with Microsoft).
